A Director of Human Resources is exploring employee absenteeism at the INCOVA Hospital. A multiple linear regression analysis was performed using the following variables. The results are presented below.

Variable	Description
Y	number of days absent last fiscal year
x1	commuting distance (in miles)
x2	employee's age (in years)
x3	length of employment at PPP (in years)
	Coefficients	Standard Error	t Statistic	p-value
Intercept	6.594146	3.273005	2.014707	0.047671
x1	-0.18019	0.141949	-1.26939	0.208391

Which of the following statements is correct about the adjusted R2?

a. The adjusted R2 value is 0.25. This means that the model explains around 25% of the variation in the average number of days absent in the last year.

b. The adjusted R2 value is approximately 0.19. This means that the model explains around 19% of the variation in the average number of days absent in the last year.

c. The adjusted R2 value is 0.50. This means that the model explains around 50% of the variation in the average number of days absent in the last year.

d. None of the above is correct.
